NODE ADDITION METHOD FOR P2P SYSTEM, CORRESPONDING P2P SYSTEM, PEER NETWORK NODE DEGRADATION METHOD AND SYSTEM, AND PEER NETWORK NODE

摘要

A P2P node access method and system. The method includes: an overload peer node or a management server acquiring a real-time performance value of a candidate client node directly connected to the overload peer node; determining a candidate client node with the real-time performance value being greater than a preset performance threshold value as a client node to be upgraded; and selecting at least one client node to be upgraded and upgrading same to a peer node, so as to solve the problem of load separation failure. In addition, a peer network node degradation method and system, and a peer network node. The method includes: a peer node to be degraded sending a leave request message to a subsequent node thereof; if a leave approval message sent by the subsequent node is received, then the peer node to be degraded degrading itself as a client node, wherein the leave approval message is sent by the subsequent node when judging that it can process the service of the peer node to be degraded according to the current processing capability thereof, so as to solve the problem that the peer node directly degrading as a client node causes the subsequent node thereof to be overloaded.
